HOSE-COUPLING.

Specification of Letters Patent.

Patented Nov. 9, 1909.

Application filed February 4, 1909. Serial No. 475,959.

To all whom it may concern:

Be it known that I, 'VINGEN P. MoVoY,

a citizen of the Unitedy States of America,

and resident of Mobile, inthe i county of Mobile and State of Alabama,have invented Vcertain new and useful Improvements 'in Hose-Couplings,of which the following is a specification.

This invention relates to vcert-ain new and useful improvements m hoseand pipe cou lings, designed primarily for use upon sma l hose such asemployed for garden hose and the like.

The present invention pertains more particularly to that class ofcouplings' of this. Vgeneral tyle in which provision 1s 4made for ingand uncoupling and in which rapid coup y are employed a plurality oflugs on the one member for coperation with lugs uponthe other, and acoupling sleeve engageable over the adjacent ends of the two members. I

The present invention has forits Vobjects among others to provideanimproved simple, yet durable and eiicient coupling of this generalnature in which exteriormem-` bers, such as stop pins and lugs aredis-fV pensed with and in which a gasket is employed which ispermanently held against accidental displacement within a socket or thelike in the end of one member and adapted to have a bearing against theadjacent end of the other member, 4saidgasket being confined within themember and held against outward or lateral movement.

The invention consists furtherin` provid- Ving coperating means'on thetwo members to center them and also to prevent relative rotation of saidmembers so that twisting of the hose is prevented from uncoupling saidmember. I provide also means for limiting the rotary movement of thecoupling sleeve upon the memberV by-which it is carried, said meansbeing concealed within the coupling ring and the groove inwhich the coerating member works.entirely.pro tected rom dust and dirt and allextraneous matters. The other memberhas a flange which serves toprevent-ingress of dirt, dust etc. to the coperating elements of the twomembers and also giving to the coupling a neater appearance andfurthermore preventing injury .to the sleeve.

Other objects and advantages of the inventionwill hereinafter appear andthe Anovel features thereof will be particularly pointed out in theappended claims.

rlphe invention is clearly illustrated in the accompanying drawings,which, with the numerals of reference marked thereon, form a partV ofthis specification, and in which- Figure l is a side elevation of myimproved coupling. Fig. 2 is a substantially central longitudinalsection through the same. i Fig. 3 is an elevation with the couplingsleeve'. removed showing a slightly modified form. Fig. l is an endpviewof the male member or nut. Fig. 5 is an end view of the other member.Fig. 6 is anend view of the coupling sleeve.

Like numerals of reference indicate like parts throughout the severalviews. Y Referring 'to the drawings l designates a member or section ofthe coupling, shown in this instance las having its exterior surfacescrew-threaded or corrugated, as at 2, in the conventional manner, andadapted for engagement within one end of a hose, not shown; The enlargedend of this member is provided with a left-handed screw thread, as shownat 3, and this thread is interrupted at a point extending approximatelyone-half of the circumference, more or less, as shown at 4, for apurpose which will be hereinafter more fully explained. The enlarged endof this member or section is provided with the oppositely disposedcurved ribs or projections 5 which extend substantially a quarter of thecircumference of the section, leaving the spaces 6 6 between adjacentends of said projections. or ribs.v These projections or ribs, insteadof extending laterally beyondthe periphery of the section, as has beenproposed heretofore, extend in the directi'on of the length of themember beyond the face end thereof, that is, they are within thecircumferential areal of the member, as seen vclearly in Figs. 2 and 3and also in Fig. 5.

7 is the opposed member of the coupling. As shown in Figs. 1 and 2,.this member comprises or constitutes a nut having apolygonal portion 8for reception of a lwrench or other implement for the purpose lofscrewing on to pipe connections, and a flange 9, as seen clearly inFigs. l, 2 and 3. The end of this member is formed with the annular`projection 10 of materiallyy less diameter than the flange 9, as shownclearly in Figs.- 2 and 3, and in the extreme end thereof is formed anannular socket or groove 11 for the reception of a packingiring orgasket 12, the wall of said groove "or socket being undercut, as

Ycompress it or expand it in a manner which will be readily understood.The annular projection is formed with the oppositely disposed lugs orprojections 14 which extend substantially each a quarter of the cirjcumference of the member, as is seen best in Fig. 4, leaving the space15 between the adjacent ends of said lugs or projections, as is alsomade-clear in said Fig. 4. The walls of these spaces are tapered, asseen clearly in "^'Fig. 4, to facilitate centering of the parts whenassembling them. The diametrically opposed end-s of the projections 14are rounded up on their inner surface, as seen at 16, to facilitate theapplication of the opggposing anges of the coupling sleeve.

As seen in Fig. 2, suliicient clearance is left, -asis indicated at 17to prevent the contact of the metal faces of the opposed members of thecoupling, so as to insure a perfectly tight joint being provided by thegasket when the parts are drawn together.

18 is the coupling sleeve or ring. It has a milled peripheral portion',as seen at 19, to aid in its being turned and is provided on i itsinterior with left-handed screw threads 20. At one end it is providedwith the oppositely disposed radial lugs or projections 21 which extendfor substantially a quarter of the circumference of the ring, leavingthe 'i oppositely disposed spaces 22 between adj acent ends of saidcoupling ring or sleeve.

23 is a screw or the like passed through the rim of the ring andengaging in the groove 4 of the member 1, as seen clearly in Fig. 2,extending a sui'licient distance to contact with the shoulders 24 formedat the ends of said groove.V It is to be understood that in assemblingthe parts, the coupling sleeve is screwed upon the threaded end of themember 1 to the required distance before the screw or pin 23 is applied,it being also understood that a partial revolution of the coupling ri-ngor sleeve is all that is necessary to securely clamp the members of ,thecoupling together and insure a water tight joint.

In operation, it being understood that the coupling ring is in positionupon the member 1 and free for revolution, limited only Vby theengagement of the screw ory pin 23,

with one or the other of the shoulders 24 at the end of the groove 4,.and that the sleeve v sleeve or ring. tion to receive the lugs 14 of themember 7 is screwed up to nearly its limit, the coupling is effected asfollows. The sleeve is turned left-handed to the stop which will bringthe lugs or projections 5 of the member 1 coincident with the lugs 21 ofthe The parts are then in posiin the spaces 6 and 22, when, by a partialrevolution of the coupling sleeve or ring, the parts are drawn securelytogether and held against movement and a perfectly water tight jointprovided. lhen in this posi` tion, the parts are held against revolutionor partial revolution with respect to each other, by reason of theengagement of the lugs 5 with the ends of the lugs 14, as will bereadily understood upon reference to Fig. These lugs 5 are in positionnot to interfere with the ready assemblage of the parts but in suchposition as to effectively prevent rotary movement of the parts whencoupled.

It is evident that the coupling may be employed for uniting two sectionsof hose and the manner in which this may be accomplished is indicated atthe left of Fig. 2, wherein 25 represents an exteriorly roughened orcorrugated member similar to the projecting portion of the member 1.

From the above, it will be seen that I have devised a simple, yetefficient, durable and easily operated coupling capable of manufactureat small cost and in which the ingress of dirt and dust to the operatingparts is excluded, and, while the structural embodiment of the inventionas herein disclosed is what I at the present time consider preferable,it is evident that the same is subject to changes and variations indetails, proportion of parts, etc., and I therefore do not wish torestrict myself to the exact details as hereinbefore described, butreserve the right to make such changes, variations and modifications ascome properly within the scope of the protection prayed.

That I claim as new is 1. In a hose coupling, a section having externalleft-handed threads and oppositely disposed projections at the endwithin the circumference and extending in a direction of the length ofthe section, a cooperating section having an annular projection withoppositely disposed lugs at the extreme outer end of said projectionwith an annular space between the same and the adjacent shoulder toreceive the projections of the first-named section, and an annularsocket, a. gasket in said socket, the spaces between said lugs beingtapered, clearance being left between the opposed metal faces of the twosections, and a coupling ring mounted upon the firstnamed section forlimited rotation.

2. In a hose coupling, a section having external left-handed threads andoppositely disposed projections at the end within the circumference andextending in the direc` tion of the length of the section, a coperatingsection having an annular projection with oppositely disposed lugs atthe extreme outer end of said projection with an annular space betweenthe same and the adjacent shoulder to receive the projections vof thefirst-named section, .diametrically disposed ends of which are roundedat their starting point and an annular socket with undercut wall, thespaces between said lugs being tapered, a gasket in said socket,clearance being left between the opposed metal faces of the two sectionsand a coupling ring mounted upon the irst-named section for limitedrotation.
